摘要： High speed scanning arrangements in scanners for reading bar code symbols by oscillating a scanner component in a single line pattern, the scanner assembly being suspended from a flexural assembly for oscillating movement. A drive is operative for moving the scanner assembly from a rest position in a circumferential direction to one of two scan end positions. The flexural assembly is tensioned and stores energy, which energy is released in order to return the scanner assembly in the other circumferential direction to the other scan end position.

摘要： An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.

摘要： An optical scanning system for reading indicia of differing light reflectivity has an optical scan module which is adapted to be mounted on a finger of a user. A first peripheral module, preferably in the form of a wrist watch, has a receiver which detects the reflected light. A second peripheral module, mounted on the other arm of the user, communicates with the first module by radio frequency transmission. According to other aspects of the invention, the light detector may be mounted in a housing which is separate and part from the optical scan module. According to another aspect, a laser pointer or scanner is mounted to a ring which is arranged to be worn on a single finger of the user.

摘要： A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

摘要： An optical scanning module has a metal base, a first circuit board mounted across one end of the metal base and a second circuit board mounted orthogonal to the first circuit board. The metal base supports a light emitter for producing a scanning beam and serves as a heat sink for the emitter. A flexible support attached to the metal base supports a mirror for oscillating motion. The module includes a drive mechanism, typically in the form of a permanent magnet and electromagnet, for producing reciprocal motion of the mirror. A detector included in the module senses light reflected from an indicia scanned by the beam. A flexible electrical cable connects the circuitry on the first and second circuit boards so that circuitry operates together to produce all signals necessary for operation of the scanner module and to process the electrical signals from the detector. Preferred embodiments include a flexible support consisting of a planar spring located between the mirror and one of the magnets. The components of the module are dimensioned so that the weight of the magnet balances that of the mirror. The invention also encompasses systems for scanning the beam simultaneously in two orthogonal directions at two different frequencies. This bi-directional scanning can produce a raster scan pattern for reading two-dimensional bar codes, or this scanning can produce a moving zig-zag pattern for reading truncated bar codes.

摘要： Optical scanning of one- and two-dimensional barcode symbols is carried out first in an aim mode wherein the symbol is scanned using a first scan pattern that is relatively small and dense so as to be visible to the user and thereafter using a second, larger and more robust scan pattern for decoding. During aiming, the symbol is partially decoded to determine type and orientation, and this information is applied to control the angle of the scan pattern produced, the rate at which the scan pattern is increased for optimum decoding, and the ultimate pattern size. Preferred scan patterns, as well as unique scan mechanisms, are described.

摘要： An optical scanner module for directing a light beam to scan an optically encoded symbol includes an optical element mounted for oscillatory motion to scan the light beam in one direction by a flex element capable of torsional flexure. This oscillatory motion is induced by the interacting magnetic fields established by a permanent magnet mounted to the flex element and an electromagnetic coil driven by an AC current. Bidirectional light beam scanning is achieved by mounting an assembly of the flex element, optical element and permanent magnet to one or more additional flex elements for oscillatory motion to scan the light beam in a second direction. This oscillatory motion is induced by the inclusion of an additional permanent magnet and/or electromagnetic coil.

摘要： A height- or width-modulated bar code is decoded by scanning an oblong laser beam across the bar code. Light reflected from the bar code varies in intensity as the laser beam traverses dark and light regions of the bar code. The bar code can be decoded by locating the valleys in the variation of intensity of the reflected light, and comparing the depth of these valleys; the deepest valleys correspond to tall or wide bars and the remainder correspond to short or narrow bars.
